An oil pipeline is a system of pipes used to transport crude oil and refined petroleum products from one location to another. These pipelines can stretch for thousands of miles, connecting oil fields, refineries, and distribution centers. They are designed to operate under high pressure and are often buried underground to minimize environmental impact and reduce the risk of accidents. Oil pipelines are crucial for the energy industry, as they provide a safe and efficient means of moving large volumes of oil. The construction and maintenance of these pipelines involve various technologies and regulations to ensure safety and environmental protection, often overseen by government agencies and industry standards.
